Abstract: PROBLEM TO BE SOLVED: To carry out the subject conversion by optimizing the relative selectivity of ethylene-propylene with an olefinic fraction derived from a steam cracking operation, etc., and further regulating the relative ratio of ethylene and propylene.  
     SOLUTION: At least one olefinic fraction selected from the group consisting of a 4C fraction and a 5C fraction is passed over a catalyst containing at least a metal selected from the group consisting of nickel, palladium and platinum and supported on a carrier at 20-220°C under 1-5 MPa pressure at 0.5-10 h -1  space velocity and molar ratio of H 2 /diolefin of 0.5-5, preferably 1-3 to carry out a selective hydrogenating step 1 and provide an effluent. The resultant effluent is then etherified with an alcohol in the presence of an acidic catalyst at 30-130°C temperature in an etherifying step 2 and separated into an ether and an alcohol simultaneously with or after the etherifying step 2 to afford an effluent. A separating step 3 for oxygenated impurities from the effluent is then carried out and propylene is separated after a metathesis step 4 for the effluent with ethylene.

Title: Data transmission method and device
Inventor: YAMAGISHI TAKASHI
IPC: H04B14/06
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To improve the data transmission efficiency by omitting partly a fixed decimal point part of continuos floating data based on a specific criterion. SOLUTION: An input signal conversion circuit 11 applies A/D conversion to an analog input signal from an external equipment such as a process equipment. A data processing section 12 converts integer data from the input signal conversion circuit 11 into data of a floating form in 4-byte and sends the converted data to a compression section 13. The standard 4-byte floating data is made up of 1-bit of code, 8-bit of exponent part and 23-bit of fixed decimal part. A compression section 13 stores data received at one preceding time, compares the data with data resulting from throwing away lower 2-bytes from 23-bit of fixed decimal part of newly received data and when the comparison indicates any change, the data thrown away by 2-bytes are fed to an encode section 14.  The encode section 14 modulates the data added a header or the like added to them through a modulator 15 and provides the output of the result to a transmission line 2.
